简介 Book Description:
Flash has always been a tool for delivering compelling and unique experiences through dynamic visual presentation. The Flash platform has grown to include application development in Flex, video streaming with the Flash Media Server, and desktop delivery through AIR, but all of that content still comes down to pixels on the screen, and all of those pixels can be manipulated through the power of the ActionScript language.
In this book, you will find in-depth coverage of the graphics capabilities of ActionScript 3.0: the enhanced drawing API in Flash Player 10 that allows you to draw vector shapes at runtime; bitmap filters and blend modes through which you can apply special, built-in effects to display objects; and the powerful BitmapData class that gives you control over all aspects of an image. In addition, you will learn about the new Pixel Bender technology and how you can use it to create custom filters and blend modes for your content through shaders. Finally, this book also breaks down the new native 3D support in Flash Player 10 and reveals how you can take advantage of this through ActionScript.
You will find that this book is much more than just a reference, though. In the later chapters, the many techniques presented in earlier chapters are all brought together. The different features of ActionScript and its graphical control are combined through a collection of tutorials to demonstrate how you can create complex and fun effects. When you put down this book at its conclusion, you should have a firm grasp of the visual manipulation possible through ActionScript and how you can apply it to your work and play.
In this book, you'll learn how to:
* Use the drawing API to create vector lines and shapes at runtime and aid in the drawing of 3D objects.
* Work with the powerful BitmapData class and use it to manipulate images and their channels and pixels.
* Use the new Pixel Bender technology to create ActionScript shaders for new bitmap filters, blend modes, and fills.
* Apply dynamic, reusable effects to images, text, and video, as well as utilize webcam video and audio as input for visualizations.
* Take advantage of open source effects and animation libraries to ease development of complex image effects.

关于作者 About the Author
Todd Yard
After studying theatre in London, then working for several years as an actor in the US, Todd was introduced to Flash in 2000 and was quickly taken by how it allowed for both stunning creativity and programmatic logic application—a truly left-brain, right brain approach to production—and has not looked back. He now freelances as a Flash developer in New York City, creating both silly animations and utilitarian applications. His personal work and experimentation can be found at his website, www.27Bobs.com.
